maxPriorityFeePerGas on Polygon should be 30 gwei by default (not 1.5 as on Ethereum)

To make it working now I do the following:

const { parseUnits } = require("@ethersproject/units");

...

const result = await erc20Token.withdrawStart(50, {maxPriorityFeePerGas: parseUnits("30", "gwei").toString()});
